Question

How do I invoke a console application from my .NET application and capture all the output generated in the console?

(Remember, I don’t want to save the information first in a file and then relist as I would love to receive it as live.)

This can be quite easily achieved using the ProcessStartInfo.RedirectStandardOutput property. A full sample is contained in the linked MSDN documentation; the only caveat is that you may have to redirect the standard error stream as well to see all output of your application.

Process compiler = new Process(); compiler.StartInfo.FileName = 'csc.exe'; compiler.StartInfo.Arguments = '/r:System.dll /out:sample.exe stdstr.cs'; compiler.StartInfo.UseShellExecute = false; compiler.StartInfo.RedirectStandardOutput = true; compiler.Start();      Console.WriteLine(compiler.StandardOutput.ReadToEnd());  compiler.WaitForExit();
